    Principles of Waveform Generation/Output The VB8300 is a digital baseband signal generator. The VB8300 loads the waveform data that you create to the waveform memory, converts the data into an analog signal using a D/A converter, and outputs the resultant waveform. It can also output digital signals without converting to analog signals.
